Combine all the ingredients in a glass or ceramic dish or bowl. Metal may affect the flavor of the dish. If the marinade does not cover the fish, add more lime or lemon juice. Cover and refrigerate the dish for 3 hours, or until the fish is white and opaque, indicating that it has been "cooked" by the acidity of the marinade. Serve individual portions on a bed of lettuce. Although this is not traditionally done, it may be served with crackers or thin slices of French bread. Posted to MM-Recipes Digest by q591b4@ilos.net on Sep 26, 1998
